What is Close Air Support (CAS)?

• A. ISR operations to monitor battles.
• B. Deterrence and air defense coordination.
• C. Delivering air strikes against distant targets.
• D. Providing direct air support to friendly ground forces in close proximity to enemy forces.

Answer: (D)

Close Air Support is air power used to directly assist friendly ground forces by delivering fires onto enemy forces that are in close proximity to those troops. The essential idea is immediate, on‑scene support: aircraft respond to ground requests and provide weapons or guided munitions to protect troops, suppress an attack, or destroy threats that are right beside or among friendly forces. This requires tight coordination with ground controllers (like a JTAC or FAC) to ensure targets are accurate and risks to the troops and civilians are minimized. The other options describe different activities: gathering information via air, coordinating deterrence and air defense, or striking targets that are far away. Those are important in their own right, but they do not capture the direct, close-by assistance to ground forces that characterizes Close Air Support.
